This catalogue accompanies the exhibition In Celebration: A Recent Gift from the Photography Collection of Marcuse Pfeifer, held at the Samuel Dorsky Museum of Art at the State University of New York at New Paltz, from February 9–July 14, 2019. It features an in-depth interview with Marcuse Pfeifer conducted by Wayne Lempka, and reflections by Timothy Greenfield-Sanders, Bill Mindlin and Wayne Lempka. Though these writings, Pfeifer's career as one of the first gallery dealers in New York City to exclusively show photographs beginning in the late 1970s is explored.
